D.R.I. (Dirty Rotten Imbeciles) is a crossover thrash band that formed in Houston in 1982. D.R.I. integrated their hardcore punk roots with thrash metal influences and were a stylistic catalyst for their contemporaries — Suicidal Tendencies, Corrosion of Conformity, S.O.D., the Cro-Mags, Nuclear Assault and Cryptic Slaughter — alongside whom they are considered to be one of the major pioneers of “crossover thrash”, having a heavy influence on modern thrash, particularly Scott Ian and his band Anthrax.
